ACO StepDrain comes complete with a corrosion resistant 304 stainless steel HeelGuard grating suitable for pedestrian traffic.

The system is available in two sizes (940mm and 1088mm) making it ideal for almost any door size.

Supports the installation of a level threshold in accordance with the Building Regulations (see below)

ACO Threshold Drain enables installers to deliver an external accessible threshold as required by the Building Regulations. 

In England and Wales, Approved Document M of the Building Regulations covers access to and use of buildings. Volume 1 applies to ‘newly erected dwellings and dwellings undergoing material alteration only.’ In each of the three categories, external thresholds must have an ‘accessible threshold’, defined as ‘level or, if raised, has a total height of not more than 15mm, a minimum number of upstands and slopes and with any upstands higher than 5mm chamfered.’ In Scotland the same requirement is covered in Section 4.1.9 of the Scottish Building Standards. 

Where there is a level entry to a building, provision of threshold drainage is even more important to minimise the risk of water entering the property.
